The Natural Phenomena

It's a natural thing that a plant needs air, water and sun to survive. Without anyone of it, it would wilt as times passes. A little change in the weather will effect the growth of a plant too. When drought or flood happen, the plant will be destroy. In the other hand, when it is an ordinary sunny day, the plant will continue growing. Why do the life of a plant have to be control by all of them? Isn't it the plant who should be the one deciding when to live and when to wilt? But, it will never happen. The plant wouldn't be given a chance to decide it's own life as this is it's destiny.
